Whatever sand coloration you decide to go with, get a larger-grained, higher density PFS from a pool supply store. Don't be tempted to get play sand from a big box store, even though it may be less expensive.
They're usually very dusty, dirty, and gritty, requiring many good rinses. They're finer grained, of lesser density than PFS, tend to free-float into the water column when disturbed, and can easily clog up your filter impeller assemblies. They are also readily siphoned up when vacuuming, which a good quality PFS will not do.
